Application July 24, 1941, Serial No. 403,792

2 Claims.

This invention relates to a tire removing device. More particularly the invention relates to a device for removing motor vehicle tires from wheels provided with safety rims. Said safety rims, adapted to receive the bead of a tire, are in turn headed to form a groove between the inner bead and the outer wall of the wheel, which positively holds the tire in place, .even though it be deflated.

Though the wheels with safety rims are an improvement over regular automobile wheels, preventing tires from rolling ofi after blowouts or puncture, they seat the tires so securely within the grooved rim that it is very dimcult to remove the tire from the rim, when desired, with the majority of tools known to the art. The invention is particularly adapted to overcome this difliculty.

An object of the invention is to incorporate into one device a system of levers to effect a quick and efflcient removal of a tire from a beaded rimmed wheel.

A further object of the invention is to make the taining economy of production.

A still further object of the invention is to design the device to fold compactly when not in use, thus facilitating storing the same.

device of standard machined material thus ob- Further features and objects of the invention I will be more fully understood from the following detail description .and the accompanying drawing, in which Fig. 1 is a side elevation of the tire remover in use removing a tire (which is shown in section) joined as by bearing screw 20. Levers ii and it may be equipped with rubber handles 2 l, 2! or the like.

Lever l3, pivotally mounted upon lever 12 as by bearing screw 20 is adapted to lie rearwardly flush 'with lever ii and is curved to conform to the contiguous face of lever H, see .45 and'le, Fig. 2, so that its wedge-like member 22 lies under wedge it and, in use, rests upon-the upper side wall of the tire l8.

Link 23 pivotally joins lever it at bearing screws 24 and 25 with lever ii, and at the same time bearing screw 25 joins lever ii with hook member I l. The fabricated steel bar M is provided at its free end with an in-turned and preferably curved hook 25, shown in use in Fig. 1, adapted to be hooked about the outer wall of the wheel I! at a position diametrically opposite that of wedge members it and 22 of levers ii and it.

1 shows the tire remover in use, graphically illustrating the method of removing a tire from a grooved-rimmed wheel, the full line representation showing the initial position of the stated parts and the dot-and-dash outline showing the stated parts in fully operated position. The tire i8 when inflated and mounted upon the wheel i! has its beads 28 seated under pressure against the respective walls 30 of the wheel II. when deflated, either through accident such as blowout or puncture, or by purposeful design, the sturdy, unstretchable beads 28 by reason of their construction are still firmly secured within the respective grooves 29 between eachouter wall 30 and inner bead 21 of the wheel l1; resistance against dislocation from said grooves 29 arises not only because the compression of the tire and its beads within the outer walls of the wheel which is a factor where the tire is mounted on a wheel having a flat rim, and this resistance is definitely increased by the rim beads 21 of present-day safety rims.

of appropriate size for the intended use. A larger size device may be employed for truck. bus and airplane tires and a smaller size for regular passenger car use.

The lever ii is provided with a curved portion it to enable its wedge shaped terminal IE to be- When taken from stored position for use in removing a tire from its rim, the arm bar I! lies folded laterally flush with lever and isthen lowered into position to allow hook 26 of bar M' to engage the lip of the outer wall 30 of the wheel II. By grasping the now adjacent handles 2|, 2|, the parallel levers ll, I2 are placed in forward position with the wedge members I8, 22, resting on the tire diametrically opposite to the engaged hook. The handles 2], 2i on levers ll,

i2 are now drawn back in unison toward the user; by so doing'the grip upon the outer wall 29 of wheel I! is increased. The wedge members I6, 22' of said levers II and i3 in contiguous posithe lever I2 is now thrust downwardly and outwardly to eflect the lowering of lever I! which presses upon the tire ll at thelocation 22 and f forcibly pushes the tire inwardly of the wheel,

thus dislodging-the concerned tire bead 28 from the grooved rim 2! and past therim head 21 in one easy, efilcient operation.

When not in use, the hook member I of the tire remover may be swung back to lie laterally flush with lever II and may be stored for future use in such compact manner.

Whereas we-have described our invention by reference to specific forms thereof, it will be understood that many changes and modifications may be made provided they do not depart from the scope of the claims,

We claim:

1. A device'for removing a beaded tire from a mounting rim, comprising a lever having a handle thereon, the free end thereof being provided with "a curvedly pointed element, a second lever having a handle thereon and pivotally related to said first-named lever, said second-named lever having a curved formation at its pivoted end, a third lever pivotally secured to said first and said second-named levers and having a curvedly pointed element disposed immediately adiacent said first-named pointed element, and a hook member pivotally secured to said first-named lever.

2. A device for removing a beaded tire from. a mounting rim, comprising a lever having a handle thereon, the free end of said lever being provided with a curvedly pointed element, a second lever having a handle thereon and pivotally related to said first-named lever, said second-named lever having a curved formation at its pivoted end, a

third lev'er pivotally secured to said first and said second-named levers and having a curvedly pointed element disposed immediately adjacent the curvedly pointed element of said first-named lever, said pointed elements being arranged to be inserted between the rim of a wheel and the bead of a tire thereon, and a hook member, including alink, pivotally secured to said firstnamed lever and by means of said link to said third-named lever and arranged to grip the rim of the wheel at a location opposite that gripped by said curvedly pointed elements, whereby upon lowering of the second-named lever the thirdnamed lever is arranged to remove the tire bead from-the wheel rim.
